POF-LINK EGS-5446 switches are gigabit switches and framed on the new-generation Broadcom chip, are developed by POF-LINK for working in high-performance network groups and enterprise’s networks. They have 24 SFP gigabit optical ports and 4 optional TX/SFP gigabit ports
POF-LINK EGS-5446 switches can access all Ethernet or fast-Ethernet devices, EGS-5446C can not only provide workgroups or enterprises those connections with high bandwidth, high performance and multi-media, but meanwhile enhance the capacity of the server group so that users can save the whole network resources rapidly. The application of it can settle the transmission bottleneck resulting from insufficient network bandwidth and rapidly increasing users, but the cost to apply it is low and the management is relatively simple.
64Gbps backboard bandwidth, uncongested design and full wire-speed orwarding,Gigabit optical-fiber transmission with up to 80Km distance and directly connecting the MAN backbone network.
High security and reliability
Providing multiple user authentication modes such as 802.1x authentication
Powerful ACL and hardware supporting L2 to L7 data filtration
Special ARP invasion detection to effectively stop ARP cheat
Flexible and various management
The straight-through cable and the intercrossed cable can be automatically identified.
Adopting the cluster technology; supporting device cascading; managing uniquely through a unique IP address; saving address resources
Multiple management modes such as Console port, Telnet, Web and SNMP are supported.
Supporting multiple general network management protocols like Broad Drictor, HP Open View and Cisco Works 2000
Powerful flow and broadcast management
The detection of IGMP packets is supported.
The flow control can be realized in full-duplex mode or half-duplex mode.
The rate limitation in a minimum step of 64K is supported on the Ethernet interface.
IP multicast and QoS are supported.
24 1000M SFP,4 ports 10/100/1000M TX/SFP,which are multiplexed with the first 4-ports,One Console port
Full wire-speed filtering and forwarding
Backpressure is adopted for half-duplex, while IEEE802.3x is adopted for full-duplex.
The broadcast storm is constrained. When the threshold value for controlling the broadcast storm is reached, the broadcast packets are stopped from being forwarded.
Automatically monitoring IGMP packets
Two transmission queues on each port are mapped to eight priority values of 802.1p.
Eight interfaces can be bound in a group through dynamic LACP or static aggregation, and 12 groups can be supported simultaneously.
IEEE 802.1D-1998 spanning tree, path backup, IEEE 802.1w(RSTP)
Supporting port-based VLAN, 802.1Q-labelled VLAN and dynamic VLAN configuration through GVRP
Number of VLANs
Supporting ACL, flow classification on L2 to L4
Supporting CLI, Telnet, SNMP and RMON
Supporting multiple general network management software
IEEE 802.1x, port-based access control, RADIUS, TACACS
DHCP snooping on the hardware,Supporting DAI and static/dynamic ARP prevention on the hardware ,
Supporting IP ACL, MAC ACL and Vlan ACL on the hardware
AC current: 110-240V (auto-adaptable), 47-63Hz, 1A/230V, or 60V broadcast & TV power
Power indicator, system indicator, connection/data forwarding indicator, 10/100M indicator
Temperature and humidity
Working temperature: 0-50?
Storage temperature: -40-70?
Humidity: 0-90% no condensation
Along with the development of network, bandwidth upgrade is now an unstoppable trend.The fashion of gigabit access and “gigabit to desktop” is realized in more and more application sites, and it can be forecasted that the L2 gigabit switches will play a more and more important role in network development in the future.POF-LINK EGS-5446 switches not only meet the requirements of network upgrade, but also make it easy for network administrators to manage and control the network through their functions like ARP filtration and ACL.
